What weight oil are you guys using?
I bought some 15W-50 Mobil 1 for my pending SC installation. I'm influenced by my experience with air-cooled engines (VeeDubs and Harleys), where you want a higher viscosity oil (preferably single grade) due to high heat. Is 15W-50 overkill? Maybe I should go with 10W-30 and an oil cooler?

Sorry for the newb question... but you change the filter (at 3k) "without" changing changing the oil? Or am i misunderstanding you.

Syntec 5w50 and Nissan OEM filter changed every 2.5k.

Re: Re: What weight oil are you guys using?
Thanks for all the responses! The consensus seems to be that 30 weight synthetic is the oil of choice. I also found this:
"It is also important to note that, contrary to what many take for
granted, higher viscosity in and of itself does not translate into better
engine protection. Extensive testing has shown the opposite to be in
fact true. As long as a lower-viscosity oil is formulated to resist
evaporation and provide high film strength, this lighter oil will
actually deliver more complete protection to the engine parts, since its
more rapid circulation delivers both better lubrication per se, and far
better cooling characteristics...a critical advantage, given that oil
flow furnishes up to 30% of an engine cooling requirements. Prior to
the introduction of synthetics, however, the problem of evaporation (and
the resultant thickening of the remaining oil) was addressed primarily
by increasing viscosity. In short, don't be concerned with the
relatively lower viscosity ratings of some synthetics. Syn lubes are a
whole new ball game."

Based on this I took the 15W-50 back and exchanged it for 10W-30.

Re: Re: Re: What weight oil are you guys using?
Looks like my 5w50 has been condemned 
Then again, I've never had any issues with the stuff, and although it's not a "pure" synthetic I'll keep on using it......... unless someone here has lost a motor to it lol.

I switched to Mobil 1 5w30 before the s/c install, ended up not installing the s/c and now just run it "FOR BECAUSE"
Oh at 5K intervals. I just changed my oil wed, and after 5k miles it still looked somewhat clean

Amen to amsoil, however just as it's "bad" to switch from reg. to synthetic after too much mileage, I feel as if I would take a risk switching from "cheapo" syntec to amsoil.. so I'm staying with the cheapo stuff lol

Well... from what I've seen it's not good to switch to synth after too much usage of regular oil.... esp. in light of all the deposits that accumulate over time..

Put it this way, if someone's engine is sooo bad that the gunk is stopping leaks, your engine is probably past the point where synthetics might do something of benefit IMHO.
You can't really say it's bad to switch. What is the cutoff? 10k, 20k, 30k, 70k 100k? What if someone changed their oil regularly for 75k and the engine is spotless? But another didn't change their much at all for 45k and their engine looked like black death?
